T 0 all whom it may concern:

Be it known that I, FREDERICK H. WAG- NEH, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Hoisting and SuspensionApparatus, of which the following is a specificauon.

This invention relates to an improved hoisting and suspension apparatusespecially designed for use in building or repairing the circular wallsof gas holder sectionsalthough the device may be readily used for otherpurposes.

it is a well-known fact that the various sections of gas holders, eventhose of comparatively small capacity, are cumbersome and exceedinglydiflicult to handle, and in building the various concentric sections andplacing them with respect to each other, a very heavy expense isincurred in special riggings to enable the various parts to be handledand a large number of men must be employed to carry out the work. Thisis all dead expense and results in a considerable outlay of money tomake even slight repairs such as painting the walls of the holder.

The present invention has therefore been designed to enable these gasholders sections to be readily handled with a small number of men andthus at a minimum cost, the saving in time and labor often exceeding theprofits heretofore made on such work.

lVith these and other objects in view the invention is illustrated inthe accompanying drawings in which,'

Figure 1., shows a sectional elevation through a series of concentricgas-holder sections with my improved hoisting and suspension devicesustained by the outermost section. Fig. 2, illustrates a similar viewof the gas-holder sections and shows the device as when used forhoisting. Figs. 3 and 4; show plan views of the gas-holder sections andthe device illustrated in Figs. 1 and 2 to make it clear that inoperation, a plurality of the improved hoisting and suspension devicesare employed. Fig. 5, illustrates a front elevation of one of the framesfor carrying the hoisting devices the upper track-supporting bracketshowever, being omitted. Fig. 6, shows a plan view of the outergas-holder section and the horizontal platform frame that sustains thehoisting and suspension device. Fig. 7 illustrates an end elevation ofthe hoisting drum and devices for revolving the same. Fig. 8 shows aside view of the same. Fig. 9 illustrates a plan view of the devices forrotating the drum, and Figs. 10 and 11 show a side and plan viewrespectively of the equalizing bar that is carried by the hoistingcables.

Referring to the several views of the drawings by numerals, 1,designates a horizontal frame or support which in the present instancecomprises parallel side rails, 52, and a plurality of struts or diagonalbrace-bars, 3, which connect the side rails. Cross-bars, 4, may also beprovided to aid in securing the rails of the frame or support togetherso that it may be strong and rigid. At the inner end, the support or theside rails thereof, carry a roller or idler, 5, which is mounted so asto turn freely in a horizontal plane.

Channel bars, 6, have position at opposite sides of the horizontal frameand said bars extend substantially vertically in a plane just behind thepivot points of the horizontal roller or idler, 5. These channel barsextend both above and below the horizontal frame and their lower pendentends are rigidly connected by a crossbar, 7. Suitable brace rods, 8,also connect the channel bars, 6, and serve to hold said bars rigid withrespect to each other and thus form a vertical frame or supportextending substantially at right angles with respect to and across theinner end of the horizontal frame or support.

A horizontal channel bar, 9, rests upon and extends crosswise of thehorizontal frame or support adjacent its inner end and the ends, 10, ofthis channel bar'project slightly beyond the side rails, 52, of saidhorizontal frame, as clearly shown in Figs.

5 and 6. Rods, 11, hang pendently from the outer projecting ends, 10, ofthe horizontal channel bar and said rods have positions at the sides ofthe vertical channel bars, 6, as shown in Figs. 1 and 5. The lower endsof these pendent rods, in the present instance, are provided with eyes,12, see. Figs. 1 and 2, and these eyes are engaged or receivehorizontally-projecting bolts or pins, 13, that are carried at the lowerpend ent ends of the channel bars, 6, and thus the vertical frame orsupport is sustained by the rods, 11, from the channel bar, 9, on thehorizontal frame or support. Suitable inclined stay bars, 1 1, connectthe bars, 6, and 2, of the horizontal and vertical frames and these barsare so attached by bolts which pass through suitable perforations orholes, 15, in the horizontal frame as to permit of their detachment fora purpose presently to be described.

The upper ends of the vertical channel bars, 6, are provided withvertical slots, 16, see broken lines in Fig. 7 through which ahorizontal drum shaft, 17, on which a drum, 18, is mounted projects. Abracket frame, 19, having a horizontal base, 20, and vertical sides, 21,fits snugly between the upper ends of the vertical channel bars, 6, andis rigidly secured thereto by means of bolts, 22, as shown in Figs. 7and 8. The drum-shaft, 17, and drum, 18, are sustained at the upper endsof the vertical sides of the bracket frame while slotted plates, 23, arefitted over the projecting ends of the shaft, 17, and are secured to theupper ends of the channel bars, 6, so as to hold the drum-shaft inplace.

The drum, 18, may be either a single continuous drum or it may comprisetwo drum surfaces as shown, and the mechanism for imparting a rotarymotion to the drum may vary but in the present instance a worm wheel,24, is mounted rigidly with respect to the drum and drum shaft so as toturn in a vertical plane while a Worm, 25, is mounted in suitablebearings, 26, on the horizontal base, 20, of the bracket frame. In thepresent instance the outer end of the worm shaft, 27, is provided with ahead through which an operating rod, 28, freely passes and by means ofthis rod the shaft and worm may be revolved.

The upper ends of the channel bars, 6, sustain a yoke frame, 29, whichis formed in the present instance by two angle-iron bars, 30, the upperends, 31, of which are rigidly secured together, while their lower ends,32, diverge and extend laterally and then downwardly so as to straddlethe upper ends of the channel bars, 6. This yoke frame is preferablydetachably connected to the channel bars, 6, so that the same may bereadily disconnected from the vertical frame or support, of which thechannel bars form a part, either for transportation or other purposes.Suitable brace rods, 33, and, 3 1, serve to maintain the rigidity of theyoke frame by connecting the latter with the side rails, 2, of thehorizontal frame, as clearly seen in Fig. 1.

The upper end of the yoke frame is provided with perforations or boltholes, 35, and a triangular-shaped bracket, 36, is secured to the upperend of said yoke frame by bolts or other fastening devices which enterthe holes, 35.

\Vhen building or repairing gas-holder sections a plurality of devicessuch as heretofore described are employed, the number varying accordingto the size of the gasholder and in order to operate expeditiously it isdesirable that an overhead trackway or rail, 37, be provided on which asuitable traveling carriage, 38, may travel so as to sustain heavyoperating tools. By reference therefore, to Fig. 1 it will be seen thatthe overhead trackway or rail, 37, is sustained by the triangularbracket, 36, while the tool-sustaining carriage, 38, is mounted so as totravel thereon. In the present instance a suitable tool-sustainingdevice, 39, is suspended from the carriage, 3S, and a tool, 40, hangspendently from said tool-sustaining device.

In Fig. 2, the horizontal and vertical frames, and the hoisting drumdevices are shown,the upper yoke frame, bracket and trackway deviceshowever being removed. In this figure the two flexible cables or ropes,a l, from the drums are shown connected to an equalizing bar, 42, whilea single cable or rope, 43, extends from said bar and is provided at itslower end with a suitable coupling device, 1 1, that may be engaged withthe gas-holder sections to lift the latter. It is deemed desirable atthis point to merely mention the fact that the various gas-holdersections are usually provided with a plural ity of man-holes and that inplacing the various sections in position the man-holes aline so that thecoupling devices, at, may be readily attached or detached by reachingthrough the man-holes.

The operation of the device will now be described reference being madeparticularly to Figs. 1 and 2. The gas holder is of the usualconstruction and comprises the innermost section, 4-5, which has a crownor dome, 16, and is also provided with a U-shaped hook flange, 17, atits lower end for purposes obvious to those skilled in the art. Thesurrounding sections, tS, may vary in number, but in the presentinstance four of such sections are shown. The outermost section, 49, isprovided with a flat circular platform, 50, at its upper end and thissection and its platform are built first in the construction of agas-holder. The platform, 50, is then utilized for sustaining theimproved apparatus,the horizontal frame or supports, 1, resting on saidplatform at intervals around the gas holder sections and being heldthereon by means of a clamp hoolc, 51, which passes through a cross bar,52, 011 top of the horizontal frame and has its hook end engaged with anangle plate, 53, at the outer edge of said platform. This manner ofsecuring the horizontal frame or support on the platform, 50, enables orpermits a ready horizontal adjustment of said support with respect tosaid platform to project the inner operating end of said support overthe various gas-holder sections as the work progresses.

By comparison between Figs. 1 and 2 it will be seen that not only maythe horizontal frame be adjusted in a horizontal direction with respectto the platform, 50, but the vertical frame or support may also beadjusted with respect to the horizontal frame so that its upper end maybe made to assume a vertical or an inclined position as desired. It willalso be noted that the central portion, 54;, of the vertical support isbowed or has position in a plane slightly beyond a line that would bestraight from end to end of the frame so that the lower end of thevertical frame may be maintained against the wall of the section, 49,while its upper end may be vertical or inclined with respect to thehorizontal frame. The adjustment of the upper end of the vertical frameis effected by a horizontal movement of the horizontal frame and anadjustment of the lower ends of brace bars, 14, 33, and, 34, along theside rails, 2,-the holes, 15, in said side rails being provided for thisadjustment. As the building or repairing of the sections progresses, theadjustment of horizontal and vertical frames is made so as to enable thework to be done rapidly.

lVhile the horizontal and vertical frames are in the present instanceformed of structural iron they may readily be constructed in a form thatmay not accurately be termed a frame and it is to be understood that theword frame as herein used is intended to include any form of horizontaland vertical, or substantially vertical, supports that coact so as toperform the operations herein described, it obviously being my intentionto so combine the two supports as to enable their adjustment to meet therequirements as the work of building or repairing the gas-holdersprogresses.

It is also to be understood that the word vertical as applied to one ofthe frames or supports is intended to mean an upright frame or supportwhich may have a vertical or an inclined position with respect to saidhorizontal frame or support.

Having thus described my invention what I claim and desire to secure byLetters Patent 1s,

1. The combination with the horizontal frame, of an upright frameprojecting above and below the horizontal frame and having spaced-apartupright bars, means hanging pendently from the horizontal frame andconnecting the spaced-apart bars of the upright frame and hoistingmechanism sustained between the bars of the upright frame and above thehorizontal frame.

5. The combination with the horizontal support of a revoluble membersustained adjacent one end of said support, an up right supportsustained from the horizontal support,said supports being adjustablewith respect to each other and a hoisting mechanism carried by theupright support above the said revoluble member.
